Energy Transformations

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically measured relative to a reference point. It is highest when the object is at its highest point.

At which position does a roller coaster cart have the most gravitational potential energy?

Back

Position W, which is the highest point of the roller coaster.

Front

What is the energy conversion that occurs when gasoline is used in a car?

Back

Chemical energy is converted into mechanical energy.

Front

What type of energy conversion is represented by the process: Chemical → heat?

Back

This represents the conversion of chemical energy into thermal energy, often seen in combustion processes.

Front

What type of energy conversion is represented by the process: Light → chemical?

Back

This represents the conversion of radiant energy (light) into chemical energy, as seen in photosynthesis.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, including light, which can be absorbed and converted into other forms of energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, which is used to do work.

Front

What is thermal energy?

Back

Thermal energy is the internal energy present in a system due to the kinetic energy of its molecules, often felt as heat.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, which can be released during a chemical reaction.

Front

What is the principle of energy conservation?

Back

The principle of energy conservation states that energy cannot be created or destroyed, only transformed from one form to another.
